Abstract: A telephone hook switch arrangement includes a base assembly (1) and a T-shaped hook switch lever 3, which is substantially T-shaped. One end of the cross-piece of the T is pivoted to a downwardly-extending portion (2) of the base assembly. At the upper end of the leg of the T, pins (e.g. 8) are on each side, each fits under the end of a moveable contact (e.g. 5). The lever also has a spring strip 10 integral with it and normally under tension. The drawing shows the arrangement when off-hook, in which case the spring strip (10) urges the arrangement to the condition shown. When on-hook, the handset, via another linkage (not shown) urges the lever (3) to the state shown in dashed lines, when the contacts are open.
